sin 30+ sin 60+sin 90÷ cos 30 + cos 60 + cos 90 Brainly.in
A 30-60-90 triangle is a right triangle with angles of 30 degrees, 60 degrees, and 90 degrees. It has special properties related to the lengths of its sides, which can make it very helpful when learning trigonometry. The ratios of the side lengths are constant for all 30-60-90 triangles: the side opposite the 30-degree angle is half the length of the hypotenuse, and the side opposite the 60.

Trigonometry. Trigonometry is a branch of mathematics concerned with relationships between angles and ratios of lengths. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical studies. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest.

Trigonometric Table. A trigonometric table is a table that lists the values of the trigonometric functions for various standard angles such as 0°, 30°, 45°, 60°, and 90°. Trigonometric table comprises trigonometric ratios - sine, cosine, tangent, cosecant, secant, cotangent. These ratios, in short, are written as sin, cos, tan, cosec, sec, and cot.

The value of Sin(30) holds significance in the analysis of special triangles like the 30-60-90 triangle and in geometric calculations. This is where Sin(30) comes into play. The value of the sine of the 30-degree angle, mathematically expressed as Sin(30), is equal to 1/2. This means that the short side will be half the length of the hypotenuse.

The sine values in degrees oscillate from -1 to +1. The angles between 0° and 90° have positive values starting from 0 and ending at +1. All values of the sine in degrees repeat cyclically. You can calculate them with the following relationships: sin (α + 90°) = sin (90° - α); sin (α + 180°) = -sin (α); and.
